About this item

  • LoRa Technology for Unmatched Range: Say goodbye to WiFi congestion! YoLink devices operate using LoRa, a long-range, low-power wireless protocol, allowing placement in challenging locations such as basements, fridges, gun safes, or barns—areas where WiFi cannot reach. While the device itself does not require WiFi or internet, a YoLink Hub (which requires an internet connection) is necessary, ensuring reliable monitoring with a range of up to 1/4 mile in open air.
  • Supports 2-Year Data Tracking: Access up to 2 years of historical temperature and humidity data through the YoLink app. Review trends and export detailed records for analysis, ensuring you have comprehensive insights into your environment over time. Perfect for monitoring long-term conditions in critical areas such as nurseries, storage spaces, or greenhouses.
  • Advanced Sensor Data Storage: This sensor features a robust data storage capability, recording activity at intervals as frequent as every 15 minutes. Even when not connected to the internet, the sensor can store over 64,000 events locally, ensuring no data is lost. Once reconnected, all stored data is automatically uploaded to the cloud, providing seamless and uninterrupted tracking of temperature and humidity conditions.
  • High-Precision Swiss Sensors: Featuring factory-calibrated Sensirion digital temperature and humidity sensors, this device provides reliable readings to NIST standards. Typical accuracy of ±0.2°C (±0.36°F) and ±2% RH ensures accurate monitoring of indoor environments without the need for manual calibration.
  • Precise Temperature & Humidity Monitoring: Monitor temperature and humidity levels in real-time with high precision. Based on the sensor's refresh rule, temperature and humidity data are updated periodically to ensure accurate and reliable readings. Whether it’s your home, greenhouse, bedroom, nursery, or storage area, the sensor continuously syncs with the YoLink app, helping you maintain optimal environmental conditions tailored to your needs.
  • Customizable Alerts & Notifications: Set personalized thresholds for temperature and humidity, and stay informed with text, email, or push notifications. Apple users can enable "Critical Alerts" to override silent mode for urgent updates. Includes up to 10 free SMS notifications per month with one hub and one sensor.
  • Battery-Powered with Extended Lifespan: Powered by two AA batteries, the sensor delivers up to 5 years of continuous operation, depending on usage and environmental conditions. Receive real-time low battery alerts via the YoLink app, ensuring you're notified when it’s time for a replacement. Designed for convenience, its long-lasting battery life minimizes the need for frequent replacements, making it perfect for hard-to-reach areas and critical monitoring applications.
  • IFTTT & Alexa Integration: trigger IFTTT applets based on high or low temperature set points reached (when device alerts). Voice query Alexa for the temperature (only; humidity not supported at this time). Triggering Alexa routines is not supported at this time.
  • Hub Required for App Functionality: To use the YoLink app and access advanced features, the YoLink Hub is required. The hub connects to the internet and serves as the bridge between the device and the app (YoLink Cloud). Hub included in this kit.

YOLINK is proving to be a very versatile environment. I have purchased several temperature gauges, leak detectors, contact sensors, a hub, and each of these products has exhibited fantastic results. They are easy to set up and to date have been very reliable. No regrets.

I am an avid user of Yolink products and have 80+ Yolink devices of varying types active.I am migrating from Switchbot Hygrometers to Yolink mainly due to the inability of SB devices to reliably connect to their Bluetooth hubs for tasks like setting alert thresholds and updating firmware remotely.Initially I have moved to Yolink YS8003 hygrometers due to their low cost, but ended up scratching the migration due to YS8003's very poor LCD display. Yolink is really a reliable ecosystem in my experience. So I've gave it another try with this Yolink Hygrometer with 2 year history (UPC 810121542132).(Note I am comparing this unit with another Yolink's low cost unit YS8003 below, which I do not recommend)This unit, although pricier, is a far better than YS8003. For one, the LCD is far superior and more readable in varying angles and lightings. Secondly, a feature difference that may not be apparent from product description is that the lower cost units like YS8003 record temperature/humidity changes only when a larger difference is detected within a short time. For example, a record is entered when more than 0.5C change within 1 minute. Otherwise, the YS8003 records hourly. In other words, if the temperature of the monitored location changes slowly throughout the day, you only get an hourly update with the lower cost YS8003 Hygrometer. However, with this unit, you have the ability set a recording interval regardless of temperature changes. It will simply record the temp/humidity at fixed intervals. This may or may not be a big deal depending on your needs, but I find it very useful to have granular data.Finally, there is also a Yolink X3 hygrometer at the top end. I have not yet figured out what makes it the top end Hygrometer in Yolink's setup. The X3 indoor unit has identical look to this unit, but is usually $10 higher at $40 as of this writing. From the description, this unit can do 15 minute record intervals while the X3 can do 10 minute intervals. However, the Yolink app allows me to set the record interval for this unit at 10 minutes as well. Other product descriptions seemed similar if not identical (e.g., 64K record capacity).So for Yolink hygrometers, I would recommend against the low end device (YS8003). The mid range (this unit) works great with a more legible LCD screen compared to YS8003, but seemed otherwise on par in features with the high end X3 unit.I would highly recommend this unit (Yolink Hygrometer with 2 years data storage. Sorry, couldn't find a model number on product page).
